Polydip Design Tips

• Adopt continuous welding and brazing methods. Avoid soft soldering and galvanizing.
• Open swaging, minimum gap 3mm allows coating all over. Avoid included air.
• Weld or braze all joints. Avoid crush folding which traps air.
• Provide coarsest possible thread and allow for coating thickness. Avoid small, fine threaded holes.
• Ensure gauge of metal is suitable for coating thickness. Avoid using extremely light gauges of metal.
• Space wires with gap not less than thickness of wire itself. Avoid closely spaced wires.
• Moving parts should be easily dismantled. Avoid movable fittings.
• Gauges of metal should be uniform. Avoid widely differing thicknesses.
• Bends should have a radius of not less than 1mm. Avoid severe, sharp bends.
• Internal corners need a radius of not less than I mm. Avoid sharp corners and crevices.
• Flanged connections can be coated all over. Avoid threaded pipe connections.
• Open sections allow free access for coating. Avoid powder traps.
